WHAT TO KNOW

Plan the whole back seat

  • 01Bridge the rear footwell

    The hard-bottom platform creates a flatter 53 × 24.8-inch rear-seat area.

  • 02Plan the full row

    Measure between the doors and check both front-seat positions.

  • 03Use a separate restraint

    The platform extends the seat area; it is not a crash-tested restraint.

Overview

FlatBridge combines a honeycomb-board base with a full-width fabric cover to bridge the rear footwell. Measure between the doors and check the normal front-seat positions before choosing it for a dog-only rear row. This configuration does not provide a passenger-side fold-down mode.

Where it fits

  • A honeycomb-board base spans the rear footwell.
  • The 53 × 24.8-inch full-width layout is intended for a dog-only rear row.
  • A mesh panel, two pockets and side coverage are integrated into the cover.

Measure before choosing

Compare the listed dimensions with your pet, vehicle and available storage space.

  1. Measure the rear-seat width between the doors.
  2. Check the space behind the front seats in their normal driving positions.
  3. Make sure the full-width layout suits a dog-only rear row.
  4. Check the shown seat-belt access and door-side coverage.
